“Feeling loved and supported by my family and friends, including each and everyone of you. I’ve been very overwhelmed and so grateful for all of the supportive comments and prayers,” he wrote on Instagram last week, along with a photo of himself in his hospital room. “The surgery went very well. The tumor is gone and I even got to keep 80% of my kidney We are all optimistic. Keep you updated. So grateful for all of you.”

Mathison, who also works as an "Entertainment Tonight" correspondent, revealed his kidney cancer diagnosis last week on Instagram, writing that he had a “health situation.” He also remained upbeat on “Home and Family” when he opened up about the tumor that doctors say had been growing for at least 10 years.
